Allyn from Mammoth Door &Construction did a great job repairing our garage door he replaced broken springs and the seal on the bottom of the door. He didn't come in and say you need this or need that. I recommend this company for all your repair services and your construction jobs they do a great job for a fair…
If I could give Mammoth 6 stars, I would. We needed deck repair work. Starting with the owner, Chris, who came out on the estimate-looking at the job. I felt comfortable in 5 minutes that Chris knew exactly what had to removed and repaired. He sent out a 2-man crew this past Monday who were professional. pleasant…
I’m having a full door installation done by Mammoth at the end of the month, which I’ll post separately, but in the meantime they came to service my existing door and it was amazing! Mike was able to come same day, and replaced my entire spring and the door was up and running again in 30 minutes! Fantastic service…
5 star company
We had a great experience with Mammoth Door. The spring in our garage door broke over the weekend and they were out at 9:00am sharp Monday to fix it. The technician was professional and fast. Price was very reasonable and he helped adjust our chain as well as it appeared loose after the spring broke. Would highly…
I use Mammoth for my property management company and they've done everything you can think of for me. They've done installs and all the service needed for my commercial building doors (35+ garage doors) as well as my residential properties and my personal home. Brian and Mike are top notch and know their stuff. I…
Awesome service indeed. Highly recommended. Great service and pricing.
I strongly recommend this company. Our garage door came off the track at 8pm on a Monday. It was stuck halfway down. We called for service Monday night and Allyn came out the next day. Allyn replaced damaged brackets, reinstalled the door and lubricated everything for the $150 service call. The door works great and the service was outstanding.
Service was prompt, and exceptional! Everyone we worked with was helpful and knowledgeable.
Allyn was professional, punctual, and highly knowledgeable. He repaired my garage door quickly, and the quality of his work was excellent. His pricing was also very reasonable.
Over the years I have used Mammoth couple of times for our garage doors services. We found they’re very good for their quality workmanship, pricing, and professionalism. Brian has earned our trust at the very first time and would use them and referred their services to friends.
Had them install new garage door and side door on garage. They did it quickly…a day a good price!
Brian came out to repair my broken garage door spring. Everything was great from booking the appointment to the final product! Pricing was fair and they were able to fit an appointment in quickly that worked with my schedule.
Professional every step, front desk, estimate, tech. Good quote, prompt, excellent workmanship. Door fixed done. I'm happy. Second experience with Mammoth very favorable. I thought I needed a new motor. Tech came out said “motor too new” He adjusted settings and gave YouTube site for future reference. He saved me…
Tony came by and fixed the front door. excellent service and great work by office people. would recommend.
Great service, fast, and fair pricing. Showed up within a few hours and worked a miracle on our door. Really happy.
Service off the charts! Helped me out of a real bind after hours for a $5 part. Will be my default recommendation for anyone that asks.
My garage door spring broke at 6 pm and Mammoth Door was at my home by 9 am the next day. Dan was friendly, knowledgeable and professional.
